After the former Teen Mom and budding porn star was arrested and blew over twice the legal limit on her breathalyzer test, the court decided certain precautions needed to be taken to ensure the safety of other drivers!

Farrah's car had to be rigged with what's called a vehicle interlock device.

It's basically a breathalyzer connected to her car's ignition that won't even let her start the car if she's had too much to drink! She'll have to use the device for at least six months!

We guess some people just can't be trusted to exhibit self control on their own!
